how does using 2 wireless cards help with the scanning?
I have found (for 2.4GHz), a 4-card setup to be extremely effective, setting card 1 to stay on channel 1, card 2 to stay on channel 6 and card 3 to stay on channel 11, with card 4 hopping through channels 2,3,4,5,7,8,9,10,12 and 13).
If you configure a 3 or 4 card system as mentioned above, prepare for (VERY) large gpsxml and packet files, as kismet will report every AP it hears at every GPS position it hears them at. When I went to this configuration my gpsxml files (per 1 hour timeframe, per a cron job restarting kismet) were 5-10x larger than they had been previously with multiple cards all just hopping.
I'm almost done configuration of an 8-card setup (4 on 2.4GHz, 4 on 5.8GHz) with a Raspberry Pi2 (4-core CPU, 1GB RAM). I found that the 5v, 12000mAH battery packs I had been using had trouble providing ample current for 4-cards on a hub, which lead to some instability. As a result, I've ditched the 5v battery packs and I will be using the 12V vehicle power with (3, 1 for each USB hub, and 1 for the rpi itself) dc-dc step-down circuits.
8-cards, 2 hubs, the pi, 3 dc-dc converters and a 12 fused distro all mounted inside of this

I will post a photo when it's done.
Not sure is that a good idea to share my web ui source because it's probably really bad code and done against every safety etc. rulesGreat setup. Do you have the source for the Web UI available somewhere?
No worries, it's going to be deployed on devices that are constantly offline anyway.
